WrrazCA/fy United States atent 2,763,444 BOBBIN WITH TAIL-TIE GUDGEON Lester F. Burlein, Honesdale, Pa., assignor to Cloverleaf- Freeland Corporation, Honesdale and Hazleton, Pa., a corporation of Pennsylvania Application February 28, 1950, Serial No. 146,719 16 Claims. (Cl. 242125) This invention relates to bobbins or spools but more particularly and specifically to a take-up bobbin and is a continuation in part of my earlier filed but now abandoned application Serial No. 54,655, entitled Bobbins with Tail- Tie Gudgeon.

A take-up bobbin or spool .is one about which yarn, or the like, is wound and the loaded bobbin or spool is then used as a yarn supply means for certain other textile mill operations as for instance warping operation. It is highly desirable and advantageous that the trailing end of the yarn on the bobbin be available for attachment to the leading end of the yarn on another bobbin so that when the bobbins are acting as yarn supply means an uninterrupted or what might be termed a magazine feed of yarn is provided. During the loading operation the barrel of the bobbin or spool is disposed in a horizontal plane and a horizontally disposed gudgeon or axle is provided as an axis for supporting the bobbin for rotation. Ordinarily in the use of the loaded bobbin Where the yarn goes to the warp beam or the quill the bobbin is supported so that its barrel is in a vertical plane.

The basic object of the present invention is the provision of a take-up bobbin in which the gudgeon or axle performs the dual function of acting as a bearing for supporting the bobbin for rotation on a horizontally disposed axis and simultaneously serving as a tail-tie to which the trailing end of the yarn is secured or snubbed against unwinding during the loading operation and is quickly available for attachment to the leading end of yarn which is wrapped about another and separate bobbin.

A further object of the invention is the provision of a bobbin or spool having a novel combined gudgeon and tail-tie in which the tail-tie is of a construction whereby it can be easily, conveniently and comparatively cheaply provided.

A further object of the invention is the provision of a combined gudgeon and tail-tie which is adapted for use with bobbins or spools having either a hollow or a solid barrel.

Other objects, novel features of construction and advantages of the invention will appear from the following description when read in the light of the accompanying drawings and be understood by those familiar with the art.

The inventive concept can be embodied in constructions and arrangements differing specifically from one another and several bobbins or spools embodying the inventive concept are illustrated in the accompanying drawings wherein:

Fig. 13 is a view in side elevation illustrating the manner in which the trailing and leading ends of yarn on loaded take-up bobbins are interconnected to provide continuous yarn feed for machines used in textile mill operations.

Having reference now to Figs. 1 to 6 of the drawings wherein one form of the invention, not to be considered the preferred form because first described, is illustrated, A is a hollow open-ended tube constituting the barrel of the bobbin. This barrel is circular in cross sectional configuration and has at its ends heads B and C each of which is preferably, but not necessarily, provided with a circular groove 1 to telescopically receive a barrel end.

In addition to the main heads B and C the bobbin is provided With supplemental heads D which are identical of construction and one of which is in each end of the barrel and abuts the inner face of the adjacent main bobbin head. These supplemental heads are preferably a single casting which has been machined and specifically comprise a circular disc 2 of the proper diameter to snugly fit the barrel and on their inner faces are provided with a hub-like portion 3 from which extends a hollow externally threaded collar or shank 4. A hollow interiorly threaded tube 5 extends longitudinally through the barrel and threadedly interconnects the shanks 4 of the two oppositely positioned supplemental bobbin heads D.

The hub-like portions as well as the supplemental heads are provided with a bore to provide a passageway d which is of the proper diameter to receive a pin, shaft or spindle upon which the bobbin can be mounted for warping or quilling operations.

The gudgeon, designated as an entirety by E, is composed of two parts one of which is lettered F and the other G. The part F embodies a head 7 and a collar 8 provided with a passageway or bore 9. The part G is of tubular form and has a diameter substantially the same as the diameter of the bore 9 of the part F. This element is provided with a longitudinal bore or passageway 10 and intermediate its length and exteriorly is provided with an outwardly extending circumferential flange 11 having one of its faces tapered as at 12. The assembled gudgeon is illustrated in Fig. 5 from which it will be seen that the end 13 of the part G is telescopically received by the bore of the part F. The part G is retained in the part F by a pressed fit. which is suffi-. ciently tight to prevent longitudinal displacement of the parts in respect to one another and axial rotation of the parts in respect to one another. The part F is milled out as at 14 and the flange 11 of the part G is milled out as at 15 and when the two parts of the gudgeon are fitted together these milled out parts are placed in alignment so as to provide a slot designated as an entirety by H.

The disc 2 of the supplemental head with which the gudgeon is associated is milled out to provide a recess 16 of the proper size and configuration to snugly receive the head 7 of the gudgeon part F while the collar of this part extends through a suitable opening 17 centrally provided .in the head C. Upon associating part Gof thegudgeon withthepart F it will be seen that the tapered or inclined face 12 of the flange 11 makes an acute angle with the end or shoulder 18 of the collar 8. Elhis providesa :spaceforthe reception-of yarn and will retain the yarn against displacement because of the ease With whichzthe yarn can be wedged between the tapered face and shoulder.

Each of the bobbin heads 'is suitably secured to its respective 'endof :the barrel by .a plurality iof screws 19 Wlhich;pass through the heads and have threaded engage ment with the disc portions 2 'of the supplemental head D. The bobbin head C at its edge is provided with a slot .20 which is substantially V-shaped :and :has its bottom or inner end 21 terminating.at.substantially'zthepoint whereisaidslotlmeets the outer iface of the bobbin barrel A.

:Inaddition to the foregoing .there is associated with the bobbinhead'C a plurality of elements which Ihave termed grooved buttons K. These buttons'are arranged circumferentially around the gudgeon .E in spaced relationship to one another and to the gudgeon and specifically comprise a threaded shank 22'which :passes through the 'ibob'bin head for threaded engagement with the-disc piortion12-of thesupplemental head. At theirouter ends and :above the bobbin head C each ofthese buttons is grooved asiat 23.

The bobbin .at its end opposite to that which .is providedwith the gudgeon'carries .orJit provided with only thattportionor partof'the gudgeon'F. The-:collar portion 8' thereof provides an axle for .rotatably supportingthe bobbin.

The two-part gudgeon E by reason .of its outwardly extending collar 8 provides the dual functionbf an ..axle

for rotatably supporting one end of the bobbin and acting-as ta tailatie for theend'of a piece of yarn'which is to be'wrapped on or about the bobbin barrel.

-In use the two bobbin collars are rotatably supported in horizontally disposed bearings to support the bobbin for rotation about a horizontal axis and the end of a piece of yarn to be wrapped on or about the bobbin barrel is wrapped around the gudgeon inthe -V.-shaped passageway or groove lying between the shoulder 18 of the gudgeon part F and tapered face of the flangeof the gudgeon pa'rtG. The yarn is then carried around the grooved buttons K for several turns with the yarn lying in the ;g1'00Ves:23-:of the buttons. .Fromt-a button .adja- Cent thehead groove 20 theLyarn is .carriedto andit-hrough the groove and a turn or two is taken about the bobbin barrel. The bobbin is now ready foroper-ation -.and"'the end of the yarn is held againstthe possibility ..of unwinding thus assuring a proper winding operation T011 the bobbin barrel.

Atthe .end .of'an operation and when .the' yarnend is to :he released from the gudgeon it is -often found that it is'wedged very tightly and will noteasily' or readily release. In-this :event a knife .or other suitable object is inserted. into the slot .H to facilitate cleaning .;out :any yarn which is 'itrapped or 'rtightly wedged -iin the groove of'the gudgeon.

"From the foregoing 'it will *be seen that-the bobbin can'be-assemble'd and taken apart quickly and' eas'ily. The main heads are secured to the supplemental headsbythe screws 19 'and'are also secured to this' element by-the grooved buttons K. The main heads can be easily and quickly associated with .a supplemental head 'or "detached therefrom. lThesupplementallheads have .threa'de'd engagement with the tube.5. Rotation of the supplemental headsin respect tothe tube 5 will pullthem. and the main heads they carry toward one another until the ends of the 'barrelare seatedatightlyin.thegrooves '1 inthe inner faces .of the main heads.

The arrangement 1 provides :a convenient, singtple, yet

4 of a yarn against slippage so as to assure proper winding operation.

The manner of supporting and driving the bobbin during the winding operation is illustrated in Figs. 11 and 12. The gudgeons at .the .opposite ends of the bobbin are rotatably supported in the bearing portions 25 in the ends of the fingers or arms 26. These arms in turn are suitably tpivotally mounted as at '27 .so that ;the bobbin, while being rotated .in the .manner hereinafter to be explained, can swing in a vertical plane. A roll M is associated with each bobbin. 'These rolls are suitably slowly rotated by a power -means, not shown, to rotate abouttheir.horizontallydisposed axles 28. .These rolls are fixed .and .atthe start .of the winding operation the roll, .see Fig. '12, engages the .barrel Act the bobbin but .as the winding operation continues ..and the barrel of the bobbin is filled with yarn the bobbin .istcaused to move away from the .roll which movement-is accommodatedby the described pivotal mounting .of the :bearing supporting fingers26.

.By reference to Fig. 12 it will be :seen-that-atthat end of the bobbin provided with ,acombination gudgeon and tail-tie thebearing .25 is disposed .outwardlybeyond the tail-tie making .it possible to .securelysnub .the :end ofthe yarn in the tail-tie and .to wrap theyarn about the buttons K in .the .manner hereinbefore described.

Although allinstallations and arrangements may not be identical :to that illustrated in .Figs. 1.1 and 12 in all instances themeans for supporting. the'bobbinforrotation about a horizontally disposed axis'is such that the tail-tie is accessible .to permit the yarn to be secured .therein.

Themanner ofoperation, previouslydescribed, follow ing the completion of the loading-of abo'bbin whenthe yarn thereon is being-used for warping orquilling is illustrated .inFig. 13-01? thedrawings. Forconvenience and clarity of descriptionthe two loaded bobbins are designated:as anentirety byNand O. .Eachnof them has tltS barrel .extendingina vertical plane .and is'heldagainst displacement by a vertical pin ;or spindlefit] and it is .to benoted that .theirends provided with the combination gudgeon and-.ta'il-tieE are at the lower ends of the-bobbins.

This gudgeon has a longitudinalibore 40 :in t-azlignment =with-;.and forming ;a continuation .of the barrel bore. 36.

;.The;bobbin;headfiat-the. opposite end :41; of; the barrel is provided centrally with an internally and externally collared: opening? to prov ideza hollowsocket 42 having-tan outer end 43 disposed in a plane beyond theouterifece of the head. Thesheads .zcanzbe; securedtito the barrel in accordance with :conventional practieeoas: for t'llHSt3HG3 pluralityzofrriuets .44.

The head S, like the previously described head C of the other form of bobbin, is provided with a slot 45 which extends inwardly from the peripheral edge 46 of the head a suflicient distance to position its inner end 47 in substantial alignment with the outer face 48 of the barrel. In place of the described channelled buttons K this head is provided with a circular retaining ring T the outer face of which is channelled as at 49 while its inner face is in the form of a fillet to provide a finger or thumb groove. This inner groove, acting as a guide for the fingers or thumb of an operator assists the operator in guiding the yarn end into and around the groove or channelway 49. It also assists the operator in picking up any end of yarn which may still remain wrapped around the gudgeon after the bobbin is empty. Although this retainer is referred to as a ring it does not constitute a closed ring in that its ends 50 and 51 are at spaced relationship to leave an opening 52 positioned opposite the inner end 47 of the head slot 45.

The end 41 of the bobbin is provided with a gudgeon V which in combination with the head socket 42 provides a combined gudgeon and tail-tie. This gudgeon is an elongated hollow tubular member the inner end 53 of which has a pressed fit with the socket 42 so that the bore 54 of the gudgeon is in alignment with and forms a continuation of the bore 36 of the barrel. The outer end 55 of the gudgeon V and the gudgeon R in reality form axles which are rotatable in suitable bearings which support the bobbin for rotation about a horizontally disposed axis.

Intermediate its length the gudgeon V is provided With an outwardly extending circumferential flange 56 having an inner tapered face 57 in opposed separated relationship to the outer end 43 of the head socket 42. This construction provides a V-shaped groove 58 for the reception of an end of yarn being wound about the bobbin. A yarn strand inserted into this groove will be wedged between the outer end of the head socket and the inner face of the gudgeon flange and be thereby retained against accidental displacement. The outer end 43 of the head socket is milled out as at 59 while the gudgeon flange is milled out as at 6t? to provide a slot 61. On occasion, at the termination of a winding operation the yarn end to be released from the gudgeon is wedged very tightly and cannot be easily or readily released. A knife or other suitable object can be inserted into the slot 61 of the tailtie to facilitate releasing or cleaning out any yarn which has become very tightly wedged in the groove.

The operation of this construction is similar to that previously described and comprises bringing the yarn end from the barrel through the head slot 45 and carrying it to and wrapping it about the groove in the tail-tie gudgeon so that it is snubbed or wedged in the bottom of the groove 53 and then carrying the yarn about the groove of the retaining ring T.

A further modification of the invention which provides a combined tail-tie and gudgeon appears in Fig. of the drawings wherein the bobbin head is fragmentarily illustrated at W and has formed integrally therewith a socket X provided with a bore 63. The socket has an outwardly extending end 64 and the elongated tubular gudgeon Y has a pressed fit in the socket. The outer end 65 of the gudgeon provides an axle upon which the bobbin is rotatably supported. The gudgeon is provided with a central longitudinal bore 66 and intermediate its length is externally provided with a circumferential groove 67 in which a split ring 68 is retained. The yarn end receiving and snubbing space 69 is between the inner face of this ring and the outer slightly rounded or tapered end face 70 of the head socket end 64. The space between the ends '71 and '72 of the ring will serve the same purpose as the previously described slots H and 61 in the other forms of the invention, namely, to permit the use of a suitable tool for releasing yarn which is wedged in and will not easily release from the yarn snubbing opening or groove.

Although it is not essential it is desirable in the practice of the invention to make the gudgeons of stainless steel.
